| 摘 要： | 本文利用线性不稳定性理论，分析了无粘旋转液体射流射入无界气体介质中的破碎机理。通过改变各项射流参数，着重分析了液体旋流数对射流分裂雾化的影响，同时也探讨了与各种射流条件相对应的射流分裂雾化的主导模式。其研究结果可为旋流在工程实际中的应用，特别是在直喷式汽油机中的应用提供了一定的理论依据。

| Abstract: | A linear instability theory is presented for the breakup mechanism of an inviscid swirling liquid jet issued into an unbounded ambient gas.Through changing the various parameters of jet,the effect of the swirl number on the breakup and atomization of the liquid jet was further discussed.At the same time,the corresponding dominant mode occurring under different conditions were also qualitatively analyzed and discussed.The results may be served as a theoretical guide for engineering applications,especially for direct injection gasoline engines. |
